N214FL left the ground this morning for an 18 minute flight.
Main concern was engine (water) cooling. As you know, cooling is a
compromise between drag from unnecessary air through cowling and
adequate cooling during normal flight conditions. Climbed to
1,500' before pulling back on throttle to see if coolant temp
would stop rising. It did. Still, I think I erred in too small
fluid inlet openings in the A/C evaporator cores I used for
radiators. Some more work in that area is in my future before hot
days arrive.
Cut the flight short due to a bit of smoke (didn't smell anything)
briefly observed low in the cockpit at full throttle later in the
flight. To be investigated.
